How much does XT do on each request there? I'm assuming these fundamental
steps:

1. Parse source xml file into a tree structure
2. Determine template (from <?xml-stylesheet?> ??)
3. Parse template xml file into a tree structure
4. Perform XSLT transformations.

Basically you can skip 1, 3 and 4 given caching in the right places
(unless of course one of either the source or template changes) but I
don't know how far XT (and the other XSLT implementations) go on this.
